GL1000 Gas Tank Cap

Postby William Ennis » Mon Feb 18, 2013 7:21 pm



Just curious. My gas tank cap fits onto the filler neck in a rather sloppy tolerance. I have to go all the way back to the 1950's in my memory to compare this kind of fit. The cap stays in place but it does not have that snug feeling I am used to when locking it into place. Is this typical ? My 1983 GL650 Silverwing has a real solid spring-loaded locking gas cap connection which I appreciate. But it is a different bike and I am not certain this GL1000 has a problem.

On the older filler caps, there used to be a cork gasket, or a rubber one. Is that sort of still in place? If not, it might be easier to find someone else with the same year as yours, and shape one from a cork mat or similar - I think I could even do it :o

The world is not going to finish today, as it is already tomorrow in Australia and New Zealand, and other islands of foreign nations such as Guam and Samoa.

Thanks for your reply. So, I was correct in my interpretation of how this thing feels. Sloppy is not good. I'll search for some material and fab a gasket. This thing reminds me of an old Jeep or a Ford Truck :-)

Suggestion is noted. But I have some material in my garage which I can easily cut to shape. Makes me think of the time I was delivering a Saab across country. Got to Wyoming and lost power. The diaphragm in the SU carb had blown. Stopped at a roadside telephone booth (remember those?) found a single yellow pages listing for a Saab dealer. Called and got directions. Found the 2nd big bush next to the barbed wire fence, just past the dead steer, turned left on the dirt road and drove 3 miles across the prairie. It lead to a Quonset Hut style building. A guy sporting a Wild Bill Cody mustache and goatee was inside. He was the only Saab dealer in the state. And his Quonset Hut was filled with Harley Davidson motorcycles plus 3 Saabs. He didn't have the diaphragm. But in a trash bin he had a bunch of old inner tubes. He gave us one and we used Tin Snip shears to cut a shape that fit the SU carb. Got back on the road and, several states later, delivered the car. I think I'll keep my lonely dollar in my wallet and cut my own gas cap gasket :-)

It is amazing what can be manufacured out of necessity. In the 60's and 70's while riding all over Luzon in the philippines, sections of large truck tubs were cut out and laid flat in the tote box. Then start cutting in a circle around and around until you had about a 50foot 1-1.5inch wide strip made. with there two items, you could tie on most anything that was falling off. You could repair broken shocks. You could make tube patches for flats. You cut cut diaphrams for whatever. Washer, shims, and seals could be cut from them. Although the rubber quality if very poor now complared to "real rubber" in those days, I still carry some out of habit. My bikes don't take the beatings they took there as i ride actual roads and not carabau trails. and of course things are built a bit more complicated today than they were 40-50 years ago.
